MIA's Description

The Westin Platinum Oval F-250 Super Duty Step Nerf Bar provides non-slip, secure footing for easier vehicle access. It features 90-degree mandrel bends for superior structural integrity and full steel construction for high-end impact resistance. The quality finish adds another layer of protection to the stainless steel bars. It has a semi-custom design for perfect fitment with select Ford makes and models, eliminating the need for adaptation work, and uses factory mounting slots for secure attachment.
